Sarocladium Allergy Shots: Two Species, Two Clinical Stories, and the Evidence Gap
Sarocladium encompasses S. oryzae (rice sheath rot pathogen, SE Asian and US Gulf rice belt agriculture) and S. strictum (formerly Acremonium strictum, documented cause of HP from contaminated humidifiers and water-damaged homes). No WHO/IUIS Sarocladium allergens exist and no SCIT RCT has been published. Source control and occupational exposure modification are the primary interventions; SCIT is not standardly indicated.

Sarocladium Allergy Immunotherapy: How It Works
Allergy immunotherapy is the only long-term treatment that re-trains the immune system to stop overreacting to sarocladium — rather than just masking symptoms with antihistamines or steroids. By gradually exposing the body to controlled doses of sarocladium allergen, immunotherapy shifts the underlying allergic response and produces relief that often outlasts treatment by 7–10 years.
There are two evidence-based forms of sarocladium immunotherapy used today, both built on the same desensitization principle but delivered very differently.
of sustained relief after a complete immunotherapy course — the only allergy treatment with proven long-term effect after stopping.
Allergy Shots (SCIT)
Weekly injections of sarocladium extract in a clinic, escalating over 3–6 months until a maintenance dose is reached. Continued monthly for 3–5 years. Longest clinical track record for sarocladium allergy.
- Strongest evidence base for severe and polysensitized patients
- Covered by most insurance plans
- Requires 50–100+ in-person clinic visits across the full course
- Or at home with no clinic visits— Curex’s Virtual Shot Room model delivers the same SCIT program with live video supervision by trained Curex clinical staff for the first injection from each new vial or concentration and restarts after gaps or reactions.
Allergy Drops / Tablets (SLIT)
Daily drops or dissolvable tablets containing sarocladium extract, held under the tongue at home. Same desensitization principle, delivered without injections. WHO-recognized as an effective form of allergy immunotherapy since 2001.
- Taken at home — no weekly clinic trips, no needles
- Lower systemic reaction rate than allergy shots
- Curex offers prescription sarocladium immunotherapy drops with allergist oversight
The rest of this page goes deep on allergen-specific immunotherapy with shots — protocol, efficacy data, side effects, and cost. If you’d rather skip the clinic and treat sarocladium allergy with at-home drops, see how Curex sublingual immunotherapy compares below.
What is Sarocladium?
The biology, taxonomy, and clinical fingerprint of Sarocladium — the foundation of how SCIT targets it.
Sarocladium strictum (formerly Acremonium strictum) grows as slow, compact colonies producing hyaline conidia in slimy heads. Its importance to allergy practice comes from historical Acremonium HP case reports from contaminated humidifiers.

How Sarocladium Allergy Presents
Symptoms by body system — useful for distinguishing Sarocladium sensitivity from overlapping allergies and infections.
Respiratory
- Occupational rhinitis in rice handlers and mill workers (S. oryzae exposure)
- Hypersensitivity pneumonitis from contaminated humidifiers or water-damaged buildings (S. strictum / Acremonium HP cases)
- Cough and dyspnea 4-8 hours after indoor moisture-source exposure for HP phenotype
- Non-specific rhinitis in atopic individuals with indoor Acremonium exposure
Ocular
- Occupational conjunctivitis in rice processing facility workers
- Eye irritation in indoor HP patients during peak exposure events
- Mild allergic ocular symptoms in sensitized individuals
Dermal
- Rare mycetoma from Acremonium/Sarocladium in immunocompromised patients — outside allergy scope
- Non-specific skin reactions from contact exposure in agricultural settings
- Onychomycosis from Acremonium species — treated with antifungals, not allergy management
Systemic
- Fever, chills, myalgia in HP episodes from contaminated indoor sources
- Fatigue with chronic HP if source not removed
- Weight loss with progressive HP
- Opportunistic disseminated infections in severely immunocompromised patients — not allergy scope
Sarocladium is a case of two very different clinical puzzles arriving with the same panel name. For a rice farmer in the Gulf Coast belt, I am thinking about occupational asthma and N95 use during harvest. For a patient with fever spikes and dyspnea linked to their humidifier, I am thinking about Acremonium HP from the older literature. Neither of those conversations ends with 'let's start allergy shots' — both end with addressing the source or the occupation.
When & Where Sarocladium Peaks
Allergen intensity by month and by state. Useful for timing SCIT start dates and travel planning.
12-Month Intensity
S. oryzae: peak occupational exposure September-November rice harvest season in Gulf Coast states. S. strictum (Acremonium): year-round indoor exposure when moisture sources are contaminated.· Occupational exposure duration aligns with rice crop cycle; indoor HP exposure is year-round as long as the contaminated source remains

What Sarocladium Cross-Reacts With
Patients sensitized to one allergen often react to others sharing similar proteins. This map shows the documented molecular overlaps.
Sarocladium (Acremonium) has no formally characterized allergen cross-reactivity due to the absence of registered IUIS allergens. Pan-fungal cross-reactivity via serine protease and enolase is plausible within Sordariomycetes class.
Both are indoor water-damage HP organisms; limited direct allergen cross-reactivity
Is SCIT Right for Your Sarocladium Allergy?
Answer these questions to determine whether your Sarocladium/Acremonium sensitization reflects occupational rice-belt exposure, indoor HP, or an incidental panel finding.
Which scenario best describes your primary exposure context?
The Sarocladium SCIT Protocol
SCIT is not standardly indicated for Sarocladium. For occupational rice-belt asthma where exposure modification has been optimized and symptoms persist, family-level mold mix SCIT may be considered. For HP, complete antigen avoidance is the primary intervention.
For S. strictum HP: identify and remove or decontaminate the humidifier, HVAC unit, or water-damaged area per EPA mold remediation guidelines (professional remediation for areas >10 sq ft). For S. oryzae occupational: N95 respirators during harvest and panicle handling, ventilation upgrades, job rotation for symptomatic workers.
If exposure modification is insufficient and the occupational asthma phenotype warrants SCIT, family-level mold mix SCIT on standard build-up with 30-minute observation. Mold vials separated from pollen extracts.
Maintenance per standard mold SCIT with concurrent exposure monitoring.
Extract Concentration Ladder
You progress through each vial during build-up. Concentration increases ~10x per step.
What the Research Shows for Sarocladium SCIT
No published SCIT RCT exists for Sarocladium or Acremonium. For HP, antigen avoidance is the primary evidence-based intervention. For occupational asthma, exposure modification is first-line.
- HP: Antigen avoidance — symptom resolution rate in acute-onset HP70%Fink JN, et al. Diagnosis and management of hypersensitivity pneumonitis. Am J Respir Crit Care Med 2005;172(6):712-716.
No SCIT RCT exists for Sarocladium (Acremonium). For the HP phenotype, antigen avoidance plus corticosteroids for active disease is the evidence-based approach (Fink 2005). For occupational rice-belt asthma, exposure modification is first-line. SCIT for severe occupational phenotypes where controls fail is a clinical-judgment, low-evidence option.

Sarocladium SCIT Side Effects
If mold mix SCIT is pursued for occupational Sarocladium asthma, standard mold SCIT side-effect parameters apply.
Local reactions
4 documented| Reaction | Rate | Severity |
|---|---|---|
Injection site swelling Standard wheal-and-flare | Rate 30-50% | Mild |
Large local reaction Mold protease increases rate | Rate 10-20% | Moderate |
Injection site itching Topical antihistamine helps | Rate 20-40% | Mild |
Delayed local swelling Self-resolving | Rate 5-15% | Mild |
Systemic reactions
4 documented| Reaction | Rate | Severity |
|---|---|---|
Rhinitis flare Within 30 minutes | Rate 0.5-1% | Mild |
Urticaria Antihistamine required | Rate 0.1-0.5% | Moderate |
Asthma exacerbation Peak flow check before injection | Rate 0.1-0.3% | Severe |
Anaphylaxis Prescribed epinephrine on hand; first dose and increases supervised live in the Virtual Shot Room | Rate <0.01% | Severe |
With Curex's at-home mold SCIT, the first injection from each new vial or concentration is supervised live in the Virtual Shot Room by trained Curex clinical staff, with your prescribed epinephrine auto-injector confirmed on hand before you inject. For HP patients, SCIT is contraindicated as primary therapy.
SCIT vs Alternatives for Sarocladium
For Sarocladium allergy, management depends entirely on clinical phenotype: HP (source control primary), occupational asthma (exposure modification primary), or incidental sensitization (pharmacotherapy and monitoring).
| Criterion | Source/exposure controlBest | SCIT (mold mix, occupational only) | Corticosteroids (HP) | Medications |
|---|---|---|---|---|
| Effectiveness | Primary and most effective for both phenotypes | Anecdotal — no Sarocladium-specific RCT | For active HP with documented disease | Symptomatic control only |
| 5-yr cost | Variable — remediation $500-$5,000+ | $3,500-$8,000 over 5 years | $500-$2,000 per course | $500-$2,000/yr ongoing |
| Duration | Permanent when source eliminated | 3-5 years | 6-12 weeks per episode | Ongoing |
| Convenience | One-time plus ongoing hygiene | At-home self-injection; weekly then monthly | Daily medication | Daily pills/sprays |
| Safety | No injection risks | Systemic reactions <1% | Corticosteroid side effects | Drug side effects long-term |
| Lasting effect | Permanent for HP if source removed | Uncertain for this organism | Controls active inflammation | No lasting effect |

Medications
For Sarocladium sensitization, source control (HP) or occupational exposure modification is the primary clinical intervention. Curex covers extended mold panels including Acremonium/Sarocladium for patients with indoor water damage or agricultural exposure. Curex allergists coordinate with environmental remediation and occupational health when source control is the higher-yield intervention. For patients where mold SCIT is ultimately appropriate, Curex delivers a personalized at-home allergy shot kit — serum sterile-compounded to USP <797>, with pricing confirmed in a current program quote — with the first injection from each new vial or concentration supervised live in the Virtual Shot Room by trained Curex clinical staff and a prescribed epinephrine auto-injector confirmed on hand.

Sarocladium SCIT — Frequently Asked
Quick answers to the questions patients ask most before starting treatment.
Sarocladium is the modern name for the genus historically known as Acremonium. Sarocladium oryzae was formerly Acrocylindrium oryzae, and Sarocladium strictum was formerly Acremonium strictum. Most clinical allergy literature (including published HP case reports from the 1980s through early 2000s) uses the name Acremonium because the reclassification by Summerbell and colleagues in Studies in Mycology 2011 postdates that literature. When you see 'Acremonium' in medical literature about hypersensitivity pneumonitis from contaminated humidifiers, it refers to what we now call Sarocladium strictum. On allergy panels, you may see either name depending on the age and updating cycle of the extract catalog.
No. Rice food allergy involves IgE to rice grain proteins — including Ory s 1 (alpha-amylase inhibitor), Ory s 12 (profilin), and other storage proteins in the rice kernel. Sarocladium oryzae is a plant pathogen that infects the rice sheath and panicle during the growing season, and occupational sensitization involves IgE to Sarocladium fungal proteins via inhalation. These are completely separate clinical entities. A person allergic to rice as a food has no increased risk from Sarocladium exposure, and a rice farmer sensitized to Sarocladium via spore inhalation does not necessarily have rice food allergy. Always evaluate each sensitization with its specific context.
No, and this is an interesting historical footnote. The cephalosporin antibiotic class was originally derived from Acremonium chrysogenum (historically Cephalosporium acremonium), now reclassified under different taxonomy. However, being allergic to cephalosporin antibiotics (which involves IgE to the beta-lactam ring) is entirely unrelated to being sensitized to Sarocladium/Acremonium mold spores. Cephalosporin drug allergy is evaluated through penicillin allergy graded drug challenges and skin testing per established drug allergy protocols — it has nothing to do with Sarocladium IgE sensitization on a mold panel.
If you suspect humidifier contamination with Acremonium/Sarocladium — particularly if you experience fever, chills, muscle aches, and dyspnea 4-8 hours after running the humidifier — you should stop using the humidifier immediately and seek medical evaluation for possible hypersensitivity pneumonitis. Do not simply clean and restart the same humidifier; replace it. If HP is suspected, your physician will order a high-resolution chest CT, precipitin testing (IgG antibodies to Acremonium), and possibly pulmonary function testing. Treatment is antigen avoidance plus systemic corticosteroids for active disease. For future humidifier use, choose ultrasonic or evaporative models, fill with distilled water, clean the reservoir weekly with dilute bleach, and discard every 6-12 months.
